COMBINATION WATER-BACK.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed February 10, 1914. Serial No. 817,791.

To all whom it may concern: 7

Be it known that I, ABNER M. HALL, a

citizen of the United States, residing at iii Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Combination Water-Backs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in water backs for ranges and has for its principal object to provide a water back which is adapted to be used for both coal and gas as fuel.

Another object of the invention is to pro vide a water'back which may be easily and quickly put in place in a range without necessitating the alteration of the construction of the range;

A further object of this invention is to provide a simple and effective water heating device which may be easily and cheaply constructed without necessitating the use of special tools.

WVith the above and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a view in elevation of a boiler showing the method of attaching the inn proved water back thereto and showing a water back positioned in a range, Fig. 2 is an enlarged perspective view of a water back constructed in accordance with this invention, Fig. 3 is a longitudinal sectional view of a water back constructed in accordance with this invention showing the same partially broken away to minimize the amount of space, Fig. 1 is a transverse sectional view of a waterback constructed in accordancev with this invention, and Fig. 5 is a top view, Fig. 6 is a vertical sectionalbranch pipe 5 extends as clearly shown in Flg. 1. The usual circulation pipes 6 and 7 for hot and cold water respectively are provided and are arranged to enter the boiler in the usual way. Thepipe 6 is provlded near the point where it enters the boiler with the T 8 which forms a connection for the pipe 9 which in turn is connected to the pipe 5 as clearly shown in the drawings. The free ends of the pipes 6 and 7 are provided with the elbows 10 which cooperate with the elbows and nipples 11 and 12 respectively, in forming a connection for the water back designated generally by the numeral 13. This water back is so arranged as to form one of the walls of the fire box 1 1 in the range or similar heater 15.

The water back above referred to by the numeral 13, comprises the rear wall 15 which is provided near one end with the enlargements 16 which are provided with the internally screw threaded apertures 17 communicating with the interior of the water back. The top walls 18 and 19 are formed integral with the wall 15 at its bottom extremities and extend at right angles thereto as clearly illustrated in Fig. 41. These walls 18 and 19 are connected at their edges by means of the arched wall 20 which forms the wall of the fire box against which the coal rests when the device is in place. The top and bottom walls 18 and 19 are extended as at 21 and cooperate with the end walls 22 in forming a rectangular chamber at each rear corner of the water back which opens into the interior thereof. The a wall 15 terminates short of the extensions 21 of the walls 18 and 19 and is provided at each end with the end wall 23 which is spaced inwardly from the walls 22 as clearly shown in Fig. 1 and in Fig. 2 to form an inset portion for the accommodation of gas pipes which communicate with the burner. This inset portion is only used during the time that the recesses, which will be more fully hereinafter described, cannot be used. These walls 22 and 23 are connected by-the wall 2% to prevent any escape of the liquid within the heater. The chamber 25, which is formed by the walls 15, 18, 19, and 20, has extending therethrough the wall 27 which is formed integral with the end walls of the chamber and is shaped to form the longitudinally extending rectangular, centrally located opening 26 in which the gas burner, which will be more fully heroine after. described, extends. The front side of the wall 27 is arranged to extend beyond the three opposite sides and is extended in such a Way as to terminate flush with the'ends of the rectangular casing to form aclosure therefor. V

The extensions21 of the side walls above referred to, are arranged so that a plurality of recesses 29 are formed near the corners ;0f the water back for the insertion of a gas pipe by means of which the burner is fed. This burner comprises the tubular member 30 which is provided with the tangential fiat side 31, the edges of which terminate in the wall 32 which is adapted to lie against the wall 27 of the opening 26 as clearly illustrated in Fig. t. A plurality of apertures 33 are formed in the curved portion 30 and are adapted to provide means to emit the gas which is to be burned and direct the same against the wall 27 of the opening 26. The walls forming the recesses 29 are preferably provided with the grooves 34 which are arranged to receive the edges of the removable filler plates 35 which form closures for the recesses when the inset portion is used toaccommodate the gas pipes.

It will be apparent from the foregoing,

'- that in use the water back is placed within the stoveor range in the usual manner and connected to the boiler 1 as heretofore described and as illustrated inFig. 1. Upon starting a fire within the stove or igniting the gas burner, it will be evident that the water within the water back will become heated and circulation will be set up through the pipe 6 into the boiler and back through the pipe 7. As water is drawn from the system, it will be apparent that the heated water in the water back will pass through the pipe 6 and up through the pipe 9, thence through the pipe 5 and into the hot water pipeS to the point where it is to be used, thus insuring the user of obtaining the hottest water in the system. Should it be desired to heat the water in the boiler without starting a fire in the stove or heater, it will be evident that theonly operation necessary is to turn on the gas and ignite the same which will cause the water within the water back to become heated.

' While in the foregoing there has been shown and described the preferred embodi- Oopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

ment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as claimed.

Having thus described my invention, I claim:

1. A combination water back, comprising, a hollow body provided with a longitudinal heating chamber, a burner removably secured within the heating chamber, the side walls of the water back being extended to form recesses for the reception of a gas pipe and the rear wall terminating short of the front wall to form an inset portion for the reception of pipes.

2. A combination water back, comprising a hollow body, said hollow body being provided with a central longitudinal heating chamber, the ends of the body being provided with vertical recesses for the accommodation of pipes, the rear wall terminating short of the front wall intermediate its lateral extremities to form an inset portion in communication with the recesses, and the heating chamber, and means removably secured within the heating chamber to use fluid fuel as a heating agent.

3. A combination water back, including a hollow body, said hollow body having a heating chamber extending longitudinally therethrough, one wall of the hollow body being convex, means carried by the opposite wall to connect the same with a water heating system, the ends of said body being provided with trough like vertical recesses, closures slidable in the recesses and removably secured therein, the flat wall of the ABN ER M. HALL. Witnesses SAMUEL LUSTIG, ANDREW STARKE.
